Frame's read_var function creates a gdb.Value from a given gdb.Symbol,
but obviously one needs the frame and the symbol for that.  There was
a stub in the gdb.Symbol code to do this without a frame, but it was
very limited so I removed it. Frame's function read_var uses
read_var_value which needs a frame (well, for some reads -
symbol_read_needs_frame returns a mixed bag of results).  Not sure if
it is possible to construct a value from a symbol without the frame in
all cases?
